Will the EcoFlow NextGen 220W Bifacial Portable Solar Panel work with the Goal Zero Yeti PRO 4000?
Yes. One EcoFlow NextGen 220W Bifacial Portable Solar Panel works with the Goal Zero Yeti PRO 4000: about 23.5 V on a 20°F morning against the station's 150 V limit, and about 219 W in full sun. Two panels: works (2 panels in parallel on HPP), about 438 W.
Works
1 x NextGen 220W Bifacial Portable Solar Panel into the Yeti PRO 4000 (1 panel on HPP) stays inside 13.3 to 150 V and under 30 A, even at 20F.
- The brand does not say whether its voltage limit is open-circuit or working voltage, so we check against the stricter open-circuit number.
- Needs an MC4 to HPP (Anderson Powerpole) adapter cable.

Quick answers
Will the EcoFlow NextGen 220W Bifacial Portable Solar Panel work with the Goal Zero Yeti PRO 4000?
Yes. One EcoFlow NextGen 220W Bifacial Portable Solar Panel works with the Goal Zero Yeti PRO 4000: about 23.5 V on a 20°F morning against the station's 150 V limit, and about 219 W in full sun. Two panels: works (2 panels in parallel on HPP), about 438 W.
Can I connect two NextGen 220W Bifacial Portable Solar Panel panels to the Yeti PRO 4000?
Yes, 2 panels in parallel on HPP. That gives about 438 W.
What cable do I need to connect the NextGen 220W Bifacial Portable Solar Panel to the Yeti PRO 4000?
Needs an MC4 to HPP (Anderson Powerpole) adapter cable.
Is it safe on a cold morning?
Panel voltage rises in the cold. One NextGen 220W Bifacial Portable Solar Panel goes from 21.5 V on its label to about 23.5 V at 20°F and 24.3 V at 0°F. The Yeti PRO 4000 accepts up to 150 V on the HPP.

Other panels that work with the Yeti PRO 4000
- Goal Zero Yeti PRO 4000: solar input 13.3 to 150 V on the Solar in 1 (HPP). Goal Zero does not say whether this limit is open-circuit or working voltage, so we use the stricter reading: open-circuit voltage on your coldest morning.
- Cold raises panel voltage: we add 0.30% per °C below 77F (25°C), a typical figure, since this panel does not publish its own. At 20F one panel's 21.5 V becomes 23.5 V.
- Current over the 30 A cap is safe: the station takes 30 A and you get fewer watts. We count only the capped watts.
- Max 3,000 W on this input, 3,000 W across all inputs.
- Cold-morning voltage uses 0.30% per °C, typical for crystalline panels. This panel's own value is not published.
- Expected watts are the best case in full sun. Real-world midday output is usually 60 to 80% of that.
